SAFETY LIQUID-DISBENSING APPARATUS. I

Application filed June 12, 1920. Serial No. 388,553.

' To all whom 2'27 may concern:

Be it knownthat I, GILBERT H. PooR, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Safety Liquid-Dispensing Apparatus, of which the following is a specification.

This invention has for its object the provision-of an improved apparatus for the safe dispensationof such highly combustible liquids as gasolene.

A further object is the provision of such dispensing apparatus as will effect the displacement and' dispensation of the liquid fuel by the introduction into the closed fuel storage tank ofa quantity of water or other liquid of greater specific gravity than the fuel, the quantity of fuel" dispensed belng conveniently and accurately regulated by utilization of a novel water container of predetermined capacity connected with the storage tank and having its communication therewith controlled by-avalve.

A- further object is theprovision, in an apparatus of this character, 'of a novel construction of plug for connection with the storage tank through which the water 1s conducted to the tank and the liquid dispensed therefrom.

lVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 represents aside elevation, partly in section illustrating the invention applied to a storage tank.

Fig. 2 represents an enlarged sectional view. through the plug detached from the container and tank.

Fig. 3 represents a top plan view of the plug.

Fig. 1 represents a bottom plan view thereof, and, g v

Fig. 5 is a horizontal sectional VlGW on the line 5 -5 of Fig. 2.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a conventional type of liquid fuel storage tank provided in one end with an opening 6 through which the fuel is introduced and dispensed;

Specification of Letters Patent.

Patented Apr. 26, 1921.

The apparatus for facilitating dispensation of the contents of a tank of this type consists of a plug 7 providedwith an exter nally threaded body as to snugly fit the opening 6 and having mounted for adjustment thereon a jam nut Y 8 which is adapted to be advanced against the top of the tank to rigidly maintain the plug? in an upright position thereon. The flange 9 of the plug at the upper end of the latter and the nut 8 are preferably provided with radial recesses to accommodate the jaws of a spanner wrenc for convenience in adjustment of these parts. The plug 7 is provided with a longitudinal bore 10 which is restricted at its upper terminal as at 11 and provided with two separate sets of screw threads 12 and 12% The lowermost screw threads 12 receive the threaded upper ter-' minal of a water discharge pipe 13 the lower terminal of which is turned upwardly as at 14 to insure against the admission of liquid fuel thereto.

The uppermost screw threads 12 cooperate with the threaded extremity of a sectional vertical water pipe- 15 between the portion of such size sections of which is interposed a water controlling valve 16 equipped with a conveniently operable hand wheel 17 whereby the passage of water through the pipe 15 maybe -conveniently controlled.

A water container 18 having a predetermined capacity is secured upon the flanged collar 19 secured to the upper terminal of the section shaft 15 and is adapted to receive a, quantity of water which is conducted to the interior of the storage tank 5 through the pipes 15 and 13.

The plug 7 is providedwith a second bore or passage 20 extending obliquely to and communicating at its lower terminal with the bore 10 and having screw threads 21 in its upper terminal. greater diameter than the water inlet pipe 13, provides an annular chamber in the plug 7 communicating with the oblique passage 20 through which the liquid fuel enters the The bore 10 being of pipe 22 having connection with a discharge pi1i123 by a manually controlled valve 24:.

e operation of'the apparatus is as follows. with a quantity of asolene or other relatively light combusti le liquid is engaged by the plug 7 the threaded terminal of the latter being screwed in the opening 6 in the top of the tank and secured in position The storage tank 5 having been filled l thereon by proper adjustment of the nut 8. The valves 16 and 24 are normally maintained in closed position sired to dispense a quantity of liquid fuel from the supply tank 5, a quantity of water ter are introduced in the container 18. Ac-

if it is desired to dispense'ten gallons from the tank 5. the container 18 is twice filled with water. When the valves 16 and 24 are opened the water in the tank 18 flows by gravity through thepipe 13 and into the tank 5 and, being of greater wei ht than the gasolene or other combustible fuel settles to the bottom of the tank causing upward displacement of the fuel and its consequent dispensation through the bore 10, passage 20 and pipes 22 and 23. The discharge of fuel from the pipe 23 may be instantly controlled by closing the valve 24, even before the entire contents of the container 18 has been admitted to the tank.

Relatively short sleeves 15 are preferably mounted upon the water supply pipe sections 15 between the valve 16 and the container 18 and between the valve 16 and the plug 9 whereby he container is rigidly maintained in upright position.

From the above it will be seen that I have provided a highly efficient liquid dispensing apparatus which will prevent evaporation of the gasolene, and by its novel construction eliminate all dirt and sediment from the. oil and in addition conforms to the rigid safety requirements of apparatus of this character. In the accompanying drawings, I have illustrated my invention embodied in one form by way of example, and which in practice has been found to be highly satisfactory in obtaining the desired results. It will be obvious however that other embodiments may be adopted, and that various changes in the details of construction may be resorted to by those skilled in the art without departing from the spirit and scope of the invention. It is furthermore undercordingly,

stood that the invention is not necessarily limited or restricted to theprecise elements shown except in so far as such limitations are specified in the subject matter being claimed.

What I claim is: 1. In an apparatus for dispensing liquids, a hollow plug, a water container,

a Water and when it is de-' dispense s introduced in the coni pipe.

a plug adapted for connection with a storage tank, a water container of predetermined capacity, a pipe connected with the container extending through the plug, said plug having a dispensing passage therethrough arranged above the outlet terminal of said pipe, and a dispensing pipe connected with said passage.

3. In an apparatus for dispensing liquids, a plug adapted for connection with a storage tank provided with a liquid conducting passage, a pipe extending, through and below the plug and having an upwardly curved lower extremity, a water containerconnected with the upper terminal of said pipe, the outlet terminal of said pipe being disposed in a plane below the passage in said plug, and a dispensing pipe communicating with the passage. 7

4. In an apparatus for dispensing liquids, a plug adapted for connection with a storage tank provided with a passage, a water outlet pipe extending through the plug and below the latter, a water container having a passage connected with the pipe above the plug, a valve interposed between the container and plug, and dispensing means communicating with said passage.

5. In an apparatus for dispensing liquids, a member adapted for connection with the filling opening of a storage tank and provided with a passage, a water supply pipe extending through the member and below the latter, a water container connected with the upper terminal of the pipe above the member, and dispensing means communicating with said passage,said passage being 10- catedabovethe outlet end of the water supply pipe.

6. In an apparatus for dispensing liquids, a plug adapted for insertion in the filling opening of a storage tank, a vertical pipe extending through the plug having an upturned lower extremity, said plug having a fuel conducting V passage therein located above the outlet end of the pipe, a con tainer connected with the upper terminal of the pipe above the plug, a dispensing pipe connected with the passage, and independ In testimony whereof, hereto.
